A bead of mass 100 g is attached to one end of a spring of natural length L and spring constant k=

(√3+1)‌mg

L

, where m is the mass of bead. The other end of the spring is fixed at point A on a smooth vertical ring of radius R as shown in the figure. The normal reaction at B just after it is released to move is (g = 9.8 ms ‌–2 )
